First, here's a small list of guides for downloading music using Termux. Make sure you downloaded and installed Termux from it's github.

Spotify
Tidal, Deezer, and Qobuz
Apple Music

Now, here's a small guide I made on how to share Spotify, Tidal, Qobuz, Deezer, or Apple Music links to Termux and have Termux download it:

1 - In the home directory of Termux, make a folder named "bin" by running mkdir bin

2 - Run cd bin and make a file named "termux-url-opener" by running nano termux-url-opener.

3 - Copy and paste one of the following lines into termux-url-opener:

1
2
3

zotify "$1"
cd apple-music-alac-atmos-downloader && go run main.go "$1"
cd OrpheusDL && python orpheus.py "$1"

4 - Press CTRL+X and press Y to save and exit. Termux should now show up in the share menu.

5 - If you want to use all three downloaders, copy and paste this instead:

1
2
3
4
5
6

case "$1" in
    *spotify* ) zotify "$1" ;;
    *qobuz* | *tidal* | *deezer* ) cd OrpheusDL && python orpheus.py "$1" ;;
    *apple* )  cd apple-music-alac-atmos-downloader && go run main.go "$1" ;;
        esac ;;
esac

Notes:

1. Yes, all of these downloaders support batch downloads. You're able to download full albums and playlists with them.
2. No, this does not require a rooted android device.
3. Yes it's safe. Everything here is even open source, meaning you can check the code yourself for any bad actors.
